CHECKS AND ADJUSTMENT BEFORE STARTING ENGINE
Perform the following checks before starting the engine at the beginning of the day's work to ensure that there is
no problem with the operation of the machine. If these checks are not performed properly, problems may occur
with the operation of the machine, and there is a danger that may lead to serious personal injury or death.
• Remove all dirt from the surface of the window glass to ensure a good view.
• Perform the walk-around check.
• Remove all dirt from the surface of the lens of the headlamps and working lamps, and check that they light
up correctly.
• Check the coolant level, fuel level, and oil level in engine oil pan, check for clogging of the air cleaner, and
check for damage to the electric wiring.
• Check that there is no mud or dust accumulated around the movable parts of any pedals, and check that
the pedals work properly.
• Adjust the operator's seat to a position where it is easy to perform operations, and check that there is no
damage or wear to the seat belt or mounting clamps.
• Check that the gauges work properly, check the angle of the mirror, and check that the control levers are all
at NEUTRAL position.
• Before starting the engine, check that lock lever (1) is in
LOCK position (L).
• Adjust the mirrors so that the rear of the machine can be
seen easily from the operator's seat.
• Adjust the angle of camera so that the surrounding area
can be seen clearly from the operator's seat.
• Adjust the armrest to a position for easier operation, and
fix it securely. Operation in an improper position can cause
a serious personal injury or death.
• Check that there is no person or obstacle above, below, or
in the area around the machine.
PRECAUTIONS WHEN STARTING ENGINE
The machine may suddenly move off and this may lead to serious personal injury or death. Always observe the
following.
• Start the engine only while sitting down in the operator's seat.
• When starting the engine, sound the horn as a warning.
• Prohibit other personnel to get on the machine.
• Do not attempt to start the engine by short-circuiting the engine starting circuit. This may cause fire, serious
personal injury or death.
IN COLD WEATHER
• If the warm-up operation is not performed thoroughly, and the work equipment is operated, the reaction of
the work equipment to the operation of the control levers and pedals will be slow and the movement of it
may not be what the operator intended. Be sure to perform the warm-up operation. Particularly in a cold
weather, be sure the warming-up operation is completed.
• If the battery electrolyte is frozen, do not charge the battery or start the engine with a different power
source. There is a hazard that this will ignite the battery and cause the battery to explode.
Before charging or starting the engine with a different power source, melt the battery electrolyte and check
that there is no leakage of electrolyte before starting.
START ENGINE WITH JUMPER CABLES
If any mistake is made in the method of connecting the jumper cables, it may cause the battery to explode, so
always observe the following.
